ASoC: wsa881x: Update temperature value during device down

Browse source 
when wsa881x device is down, reading temperature from driver
returns error. Instead of propagating the error, return the
cached temperature value to the thermal framework to avoid
iterative calls to read the temperature that results in
excessive logging.
